I rolled out some updated tracker code last week to help speed up IZEARanks ITK. More information about those changes can be found here. But the Systems guys just sent me a screenshot that makes me all warm inside:To the left of the first blue vertical line is the amount of load on the DB with the old tracker. The spike inbetween the two blue lines is the load on the day of deployment. The spikes, if you can see them, to the left of the blue lines are the DB load with the new Tracker in place. So with new code, and the backend systems modified (thanks Trev and Mark), the new Tracker absolutely screams!
